9mm? You might need a high capacity magazine sometimes.
.22 Magnum? Go the other way on bullet weights. The .45 and 50 gr bullets are very effective on Fox's, Coyote's and large coons.
.30 Carbine? Was better than nothing for the men in back of the line (cooks, mechanics and others) that could not be issued those very expensive 1911's. But it is definitely no battle caliber.
The Korean "ROK's" seemed to do very well with them in Vietnam. Lots of them where I was, and most seemed to be carrying them. miles
